Suppose that 13% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). Consider a random sample of 200 shafts, and let X denote the number among these that are nonconforming and can be reworked. (Round your answers to four decimal places.) a. What is the (approximate) probability that X is at most 30? b. What is the (approximate) probability that X is less than 30? c. What is the (approximate) probability that X is between 15 and 25 (inclusive)?

a)0.8280

b)0.7691

c)0.4503

Step by step Explanation:

It was Given that 13% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).Each shaft is independent of the other and probability for non conforming is the same for each trial.

If X the denote the number among these that are nonconforming and can be reworked. Then

n =200 and

p = 0.13

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
